my car wont start brand new battery, i need to know if its my starter or my ignition switch before i start replacing stuff. so how can you test for both before taking it apart.
is there a way to test your starter before trying to change it? on 2000 Pontiac Sunfire
The big wire on the starter should have 12VDC to it all the time. The smaller wire is from the ignition but first goes through relays and other wires. There should be 12VDC at the smaller wire when the key is turned to the start position. If there is no power at the small wire when turned to the start position you may have a bad starter relay which is located under the hood in fue box. Another way to check statrer which I probably shouldnt tell you because of the danger bt if you jump the large wire to the small wire with a long screw driver the starter should engage. If the key is on when you do this the car will start and run. Be careful for any moving parts. When you jump the two wire terminal there will be a spark and it is necessary that you dont keep jumpinng the terminals if you get scared and back up. Doing this could also damage the threads on the starter if you do it more then once causing it to be difficult to remove nuts if starter is bad.
ok Thanks sooo much. It is my starter. power is going to it but it wont engage.
Sometimes the Bendix in the starter gets hung up with the flywheel. If you're trying to squeeze every bit of use out of the starter, "Sometimes" and I say "Sometimes" because this is not a Guarantee, you can take a metal bar of some sort and kind of tap on the starter a few times and it will cause the bendix to dislodge and possibly get you a few more starts. That is, if that is what the problem with your starter is. Either way, I think a couple of pecks with a bar is worth a shot.
